The OCZ Vertex 3 Review (120GB)
by Anand Lal Shimpi on April 6, 2011 6:32 PM ESTOverall System Performance using PCMark Vantage
Next up is PCMark Vantage, another system-wide performance suite. For those of you who aren’t familiar with PCMark Vantage, it ends up being the most real-world-like hard drive test I can come up with. It runs things like application launches, file searches, web browsing, contacts searching, video playback, photo editing and other completely mundane but real-world tasks. I’ve described the benchmark in great detail before but if you’d like to read up on what it does in particular, take a look at Futuremark’s whitepaper on the benchmark; it’s not perfect, but it’s good enough to be a member of a comprehensive storage benchmark suite. Any performance impacts here would most likely be reflected in the real world.
If we use PCMark as an indication of light system performance, the Vertex 3 120GB does pretty well here.

Great job Anand!ARoyalF - Wednesday, April 6, 2011 - link
For keeping them honest!magreen - Wednesday, April 6, 2011 - link
Intro page: "It's also worth nothing that 3000 cycles is at the lower end for what's industry standard..."I can't figure out your intent here. Is it worth noting or is it worth nothing?

Noting, not nothing. Sorry :)Take care,
Anand

Lmao. Magreen, I like how you addressed that.Shark321 - Thursday, April 7, 2011 - link
On many workstations in my company we have a daily SSD usage of at least 20 GB, and this is not something really exceptional. One hibernation in the evening writes 8 GB (the amount of RAM) to the SSDs. And no, Windows does not write only the used RAM, but the whole 8 GB. One of the features of Windows 8 will be that Windows does not write the whole RAM content when hibernating anymore. Windows 7 disables hibernation by default on system with >4GB of RAM for that very reason! Several of the workstation use RAM-Disks, which write a 2 or 3 GB Images on Shutdown/Hibernate. Since we use VMWare heavily, 1-2 GB is written contanstly all over the day as Spanshots. Add some backup spanshops of Visual Studio products to that and you have another 2 GB.Writing 20 GB a day, is nothing unusual, and this happens on at least 30 workstations. Some may even go to 30-40 GB.
Only 3000 write cycles per cell is the reason why we had several complete failures of SSDs. Three of them from OCZ, one Corsair, one Intel.

Yours is a usage scenario that would benefit more from running a pair of drives, one SSD and one large conventional hard drive. The conventional drive could be used for all your giant writes (slowness won't matter because you are hitting shut down and walking away) and use the SSD for windows and applications themselves.Shark321 - Friday, April 8, 2011 - link
HDD slowness does matter! A lot! Loading a VMWare snapshot on a Raptor HDD takes at least 15 seconds, compared to about 6-8 with a SDD. Shrinking the image once a month takes about 30 minutes on a SDD and 3 hours on a HDD!Since time is money, HDDs are not an option, except as a backup medium.

How can you be so sure it is due to the 20GB writes per day?If you run out of NAND cycles the drives should not fail (as I'm implying you mean by your description)
When an SSD runs out of write cycles you will have (for consumer drives) if memory serves about one year before data retention is no longer guaranteed.
What that means is that the data will be readable, but not writeable
This of course does not in any way mean that drives could not fail in any other way, like controller failure or the likes
Intel has a failure rate of ca 0.6% Corsair ca 2% and OCZ ca 3%
